Description
~LZ~8S
The present inventlon relates to a s~stem ~all or system ceiling comprising a number of supporting girders suspended from the structure of the bui.lding and to which s~labs are mount0d substantially extending per-pendicular to the girders.
Such a system ceiling i5 known in which the slabs are mounted to the g~rders by means of fastenlng mem~ers clamped or pushed onto the girders and which are pro~ided with sheet metal strips directed downwardly to the slabs, and of which the end portions flanged at right angles engage s.~a~cuts applied into the sides of the slabs.
This manner of mounting the slabs to the girders has the dratyb.ack, that on occurrence of shrinkage or buckling of the slabs, these sla~s aecome insufficientl~ retained by the fastening members and may~shift with respect to each other, so that the spacing between the succeeding slabs which are generally bridged b~the so called first strips, t~ll sho~ d~fferences.
B~ the ~irst strips which, to obtain a decorative effect, may have a contrasting tint with respect to the slabs, and which also are slipped into the saw cuts at the sides of the slabs, the mutual differences in spacing between the slabs further is accented.
Also, on shrinkage of the slabs, the first strips may become free from the saw cuts, which causes a very defacing effect to the known system ceiIing.
It is an object of the present invention to remove these drawbacks of the known s~stem ceiling.

a plurality o separate slabs, each slab having at least one .~ ~
